ELIJAH YVRIGHT, OF NORTH ANDOVER, MASSACHUSETTS, ASSIGNOR TO THE DAVIS &FURBER MACHINE COMPANY, OF SAME PLACE.

CONDENSER FOR FlNlSHER-CARDS.

SPECIFICATION forming part of Letters Patent No. 340,929, dated April27, 1856.

Application filed February 8, 1836. Serial No. 191,170.

adapted to be reciprocated in guides of afra'me attached to theframe-work of the machine, aud both sets of rub'rolls are held in the I5same frame, and the stripper'rolls next to the doffers, and between themand the first top rub-roll of each set of rub-rolls, are one above theother in the same vertical plane.

To enable each set of rub-rolls, with its cooperating stripper-roll, tobe adjusted independently of each other with relation to each dofi'er,to compensate for unequal wear of the doffer, and also to adapt theposition of the rub-rolls horizontally to any variation in the positionof the doffers or to doifers differing in diameter, I have dividedhorizontally the frame carrying the rubrolls into, as herein shown, twoparts, and have arranged one upon the other, and connected the two partsadj 11st ably together.

My invention consists,essentially,in a frame containing a set ofrubrolls, combined with a second superimposed independent framecontaining a set of rub-rolls, one frame being made adjustablehorizontally upon the other at right angles to the length of ther'ub-rolls,to enable each set of rub-rolls to be placed at the properdistance from the doifer with which it is to cooperate, substantially aswill be de scribed.

Figure 1 in side elevation shows portions of a finisher-card with myimproved condenser attached thereto,the card-clothing being, however,omitted; Fig. 2, a section thereof in the line 00 x of Fig. 1, lookingtoward the left, one of the eccentric-straps, and one of the rods beingpartialy broken out, the said figure showing only that end of the twoframes at which the rub-rolls derive their reciprocating movement, theopposite ends of the said frames be- (No model ing the same inconstruction as the end frames shown, the opposite ends of the saidrolls, and the usual mechanism for rotating them, and also the guidescut by the said dotted lines,are omitted to avoid confusion in thedrawings; 5 and Fig. 8, a separate detail chiefly to show one of thespherical boxes.

A is the framework, and B the main cylinder, both of usual construction.

Prior to my invention the rubbingrolls of the condensing mechanism haveboth been placed in one frame with their axes of rotation in the samevertical line.

In accordance with my invention I divide the condenser into two or moreparts or frames, 6 as at E E, and connert the same adj ustably.

As herein shown, the connection between the separate parts or frames E Eis made by bolts a, extended through slots in the top and bottom platesof the said frames, and to provide for their adjustment when the saidbolts are loosened I have herein shown screws 6 extended through oneframe, they striking lugs 01' projections c of the other frame, the saidlugs (herein shown as attached to the upper frame, E) being extendedthrough slotsin the lower frame.

By the term frame I mean to includeuprights of like general shape atopposite sides of the carding-machine, the said uprights at oppositesides of the carding-machine'being connected, as, for instance, bya roda, orany suitable bar extended from one to the other, the said rod beingpassed through part of the upper frame, E, the lower part of the frame 85 E being connected, as usual, by bolts 62 to the frame of thecarding-machine.

The frame E has two reciprocating carriages,

d" d, which slide on guides33 and have usual bearings for the upper andlower rub-"rolls, d and d, and next to one of the upper rolls, andbetween it and the doEfer D, is located the stripper-roll d.

The frame E, mounted adj ustably upon the frame E, has usual guides, 22, for the recip- 5 rocating carriages c 0 which have bearings for thelower and upper rub-rolls, c and c and between one of the upperrub-rolls and the doft'er C is located the stripper-roll c.

The rub-rolls are reciprocated,in usual manner,by eccentrics on anupright shaft, G, having at its lower end a bevel-gear, 10, driven froma bevel-gear, 12, on a shaft, 13, common in finishing-cards. Theeccentrics 65 on the shaft G are embraced by eccentric-straps 14, therods of which embrace studs of the said carriages, and to permitadjustment of the frames the said rods are provided with holes made toresemble two cones with their apices together, as shown in section, Fig.2.

The upper and lower journals of the shaft G are made to enterholes inpipe-boxesf, which externally are made spherical, as best shown in Fig.3, to fit concaved bearings 66, having concaved capsf, the sphericalshape given to the pipeboxes enabling the shaft to be tipped out ofvertical position when the frames are adjusted one on the other to placethe rub-rolls and the stripper-rolls in correct working position withrelation to the dot'fers O and l).

I have herein shown two separate frames, E E, with their series ofrub-rolls to co-operate with two doifers; but I desire it to be under- Vstood that I may use more than two frames,

one mounted above and made adjustable on the other, each frame havingits proper set of rub-rolls, there being a doffer for each set ofrub-rolls.

I do not desire to limit my invention to the employment of theparticular mechanism shown for actuating the rub-rolls.

Instead of the particular devices shown to connect the frames E Etogether, and to adjust the same one on the other in a direction atright angles to the length of the rub-rolls, I may employ any otherwell-known equivalent devices.

The rub-rolls may be rotated by means of gearing substantially such asshown in United States Patent No. 238,329, or in other usual manner.

I claim- 1. A frame containing aset of rub'-rolls, combined with asecond superimposed independent frame containing a set of, rub-rolls,one frame being adjustable horizontally upon the other at right anglesto the length of the rubrolls to enable each set of rub-rolls to beplaced at the proper distance from the doffer with which it co operates,substantially as described.

21 Two or more doffers, two or more sets of rub-rolls,and theirco-operating stripper-rolls, combined with two or more separate frames,and carriages therein to support thejournals of the said rolls, oneframe,with its set of rubrolls and stripper-rolls,being made adjustableon or with relation to the other frame and its set of rub rolls andstripper-rolls to insure the placing of the said rub or stripper rollsat the proper distance from the said doffers, substantially as and forthe purpose described.

3. The two independent frames E E, made adjustable one on or withrelation to the other, their carriages, rub-rolls supported thereon, andthe upright shaft provided with eccentrics, and theconnecting-rods,combined with the spherical pipe; boxes, and in whichthe said shaft has itsjournals and bearings therefor, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ELIJAH WRIGHT.
